y'IO ALL WIIOM IT MAY CONCERN:

Be it known thatI, E. BATBMAN, of Frederick, in Frederickcounty, and State of Maryland, have invented a new and useful Improvement in FlourBoltingjMachines; und I do hereby'declare that thefollrwing is avffll,

clear, and exact description thereof, reference being hud to the accompanying drawing, and to letters of reference marked thereon, forming part of this speoieation, and in whichT Figure 1 represents a vertical longitudinal section, and

Figure 2 a vertical transverse section of a belting machine embracing my improvement.

'lhe same letters of reference occurring on both iguresindicate'likc parts.

This invention relatcsto that class of halting machines wherein a revolving licking-cylinder is used'in conibination with a fan arranged toi-evolve within said boltin'g-cylinder, and in 'tlie'opposite,direction from its rota...

-tion, and in which the lour, when driven by the ,force efr the blast against the inner side of the bolting-cloth, is

'p tiiefan; to be again separated and driven towards and through the bolt. J'

apt either to stick thereto, or, asttlio bolting`cylinder rotates, tojroll around on the 'lower side of the horizontal cyli.nder,vto be b'ut slightly niected, by such blast; and it consists in the application o'f a series of-buckets or ribs within thc bolting-cylindcr, so arranged as to elevate such portion of the ilour as may accumulate at the lower side of the cylinder, and, in its continuous rotation, to deliver it at appoint above the level of the axis of 'lo enable others to make and use my invention, I will vdescribe it by referring totlie drawing, in whichv A represents the casing of my apparat-us, tifhich' may be made of sheet iron, wood, or other suitable material, and at either end is Vprovid-ed with bearings a, to support the'journals of the shaft B of the fan C, which is rotated by means of a pulley,.D, driven by any suitable motor. The bolting-cylin-der E consists of the ordinaryannular rims Z1, one at cach end, and longitudinal ribs c connecting them, which serve to support the bolting# cloth d, represented in. the drawing in red' lines. ,Four or more. buckets or inwardly-projecting ribs nare attached tothe insidfr'ofthe bollingcyliiider, parallel with and connected to the ribs ycof thc cylinder. The cylinder thus constructed is supported by radial arms 4c e', those marked being located a short distance within the end of the halting-cylinder, to admit of the entrance'of the feed-'spout Fwithin the cnd thereof, whilst those marked e are connected with the opposite1 end of the said cylinder by brackets f, solas to admit of the extcm sion of the fan-blades beyond the end ofthe bolt. These radial arms c e are attached tocollars or sleeves g g',

encompassing the shaft B of the fan. The sleeve gi', extending through, and outside of, the casingv A, has v attached to it a pulley or` drum, G, by which the bolting-cylinder is rot-ated. i The casing A, aroundund beneath the bolting-cylinder, is divided, in a transverse vertical direction, into two or morecompnrtnilents, to form i receptacles for the different grades olf flour bolted, andis provided with-an aperture, h, for the admission ofair to the fan C, and which is rbgulatcd by a slide, z'.

The operation will then be as follows: The gristbeing supplied to the bolting-cylindcr through the spout the cylinder is put in motion, at the rate of about twenty-eight revolutions per minute, by nieansof a -belt or other motor applied to thc drum G; and the fan C being rotated at a velocity of from one to two hundred revolutions in the opposite direction to the motion of the cylinder E, a strong blast is created by the fan forcing the grist against the baiting-cloth; and by the rapid rotation o f the fan, its one cr'id being' lwithin the boltingi` cylinder, and its other protruding beyond'it, a strong current is createdthrough the central portion, which mayf.'

be regulated by adjusting the sliding door i, and -by which current of air the fuzz on the Acnil of -thc grain,the bran, and every particle lighter than the ilour is carried forward and expelled. l A radial blastis also caused by the fan, which, together with the longitudinal current of air -just named, causes an even distribution ofthe grist throughout thc length ofthe licking-cylinder; and, as the said cylinder rota-tes, that portion of the grist which may have settled in the lower portion of the cylinder is elevatcdvby the buckets n until they successively reach a position 'somewhat above thc level of its axis, and is again discharged towards the centre by its own gravity, to be acted on by the blastof the fan as before. If it is' dcsirodto bolt various gradcsofflouiythe boltingcylinder is constructed with sections 'of its length covered with di`erontgrades of canvas, and the chamber l enclosing it divided into compartments correspondingly. J y

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is The buckets 11, arranged and operating in combination with theboltiiig-cylinder and fan, substantially as i hcrcinset forth.

In testimony whereof I hereunto subscribe my name before two subscribing witnesses this 18th day-ofv January, 1867.. Y
